19.6.5.2 Enabling parameters
The parameters whose symbols are preceded by "*" are enabled by the following operations. Refer to chapter
5 in for the parameters with "*". Refer to chapter 5 for "*" of the parameter symbol.
(1) Network disconnection
A parameter is enabled when a network disconnection switches the driver state to the state in which it
waits for the upper side to be connected. Refer to section 1.4.3 for the procedure of network
disconnection.
(2) State transition
A parameter is enabled when the I/O connection shifts from the Run mode to another mode.
(3) Enabling a parameter with a parameter enabling object
A parameter is enabled by writing "1EA5h" in User parameter configuration (Class ID: 64h, Ins ID:
2D34h, Attr ID: 0). This operation can be performed only when the I/O connection is not in the Run mode.
The parameter enabling processing requires a maximum of about 100 ms. The following table shows the
read values of User parameter configuration (Class ID: 64h, Ins ID: 2D34h, Attr ID: 0). By checking the
read value, the completion of the parameter enabling processing can be checked.
